IMPROVEMENT IN SNAP-HOOKS.

Specification forming part of Letters Patent N0- 183,460, dated October17, 1876; application filed September 15, 1876.

To all whom it may concern:

Be it known that I, GEORGE M. HUBBAED, of New Haven, in the county ofNew Haven and State of Connecticut, have invented a new Improvement inSnap-Hooks; and I do hereby declare the following, when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part. of this specification, andrepresent in Figure 1 a side view, and in Fig. 2 a longitudinal section.

This invention relatesrto an improvement in what are commonly termedsnap-hooksL that is to say, a hook provided with a latch mechanism,which will hold the hook in engagement with whatever. it may be hookedupon to prevent its accidental removal.

It consists in a body, one end terminating in a hook, the other in aloop or means for, attaching the hook to a strap, or whatever it may be,the said body constructed with a recess or chamber in the plane of thehook, and combined with a hook or U-shaped latch hung l, upon a pivot atits lower forward end, and a spring, the bearing-point of which isforward of the said pivot, as more fully vhereinafter described.

A is the body of the hook, one end terminating in the'usual hook B, andthe other in the usual loop C. The body is constructed with a slot orchamber, a,-in the plane of the hook, and into this theme11 n is placed.This.

latch is of U form, the lower forward end hung upon a pivot, d, theupper forward end e resting against the end of the hook. Forward of thepivot d a spring, E, (preferably a spiral spring,) is arranged to bearupon a portion of the body of the hook, and also on a seat on -the latchforward of the pivot, as shown in Fig. 2.

The upper or outer surface of the latch is, preferably, serrated orroughened,.as a convenient means for opening the latch. To open thelatch, the thumb is placed upon this roughened surface and drawnbackward to turn the hook'from the loop, as seen in Fig. 2. The

spring automatically Vcloses the latch when free.

I claimv The herein-described snap-hook, consisting of the body,terminating at one end in a hook, and at the other in means forattaching the hook, combined'with a hook or U -shaped latch hung withinthe body upon a pivot at its lower forward end, With a spring, thebearingpoint of which is forward ol' the said pivot, and the upper endot' the said latch closing against the end of the hook, allsubstantially as set forth.

GEORGE M. HUBBARD.
